+
+## Overview
+
+To derive `clap` types, you need to enable the `derive` feature flag.
+
+See [demo.rs](../demo.rs) and [demo.md](../demo.md) for a brief example.
+
+Let's start by breaking down the anatomy of the derive attributes:
+```rust
+use clap::{Parser, Args, Subcommand, ValueEnum};
+
+/// Doc comment
+#[derive(Parser)]
+#[clap(APP ATTRIBUTE)]
+struct Cli {
+ /// Doc comment
+ #[clap(ARG ATTRIBUTE)]
+ field: UserType,
+
+ #[clap(value_enum, ARG ATTRIBUTE...)]
+ field: EnumValues,
+
+ #[clap(flatten)]
+ delegate: Struct,
+
+ #[clap(subcommand)]
+ command: Command,
+}
+
+/// Doc comment
+#[derive(Args)]
+#[clap(PARENT APP ATTRIBUTE)]
+struct Struct {
+ /// Doc comment
+ #[clap(ARG ATTRIBUTE)]
+ field: UserType,
+}
+
+/// Doc comment
+#[derive(Subcommand)]
+#[clap(PARENT APP ATTRIBUTE)]
+enum Command {
+ /// Doc comment
+ #[clap(APP ATTRIBUTE)]
+ Variant1(Struct),
+
+ /// Doc comment
+ #[clap(APP ATTRIBUTE)]
+ Variant2 {
+ /// Doc comment
+ #[clap(ARG ATTRIBUTE)]
+ field: UserType,
+ }
+}
+
+/// Doc comment
+#[derive(ValueEnum)]
+#[clap(ARG ENUM ATTRIBUTE)]
+enum EnumValues {
+ /// Doc comment
+ #[clap(POSSIBLE VALUE ATTRIBUTE)]
+ Variant1,
+}
+
+fn main() {
+ let cli = Cli::parse();
+}
+```
+
+- `Parser` parses arguments into a `struct` (arguments) or `enum` (subcommands).
+- `Args` allows defining a set of re-usable arguments that get merged into their parent container.
+- `Subcommand` defines available subcommands.
+ - Subcommand arguments can be defined in a struct-variant or automatically flattened with a tuple-variant.
+- `ValueEnum` allows parsing a value directly into an `enum`, erroring on unsupported values.
+ - The derive doesn't work on enums that contain non-unit variants, unless they are skipped
+
+See also the [tutorial](../tutorial_derive/README.md) and [examples](../README.md).
+
+## Attributes
+
+### Terminology
+
+**Raw attributes** are forwarded directly to the underlying `clap` builder. Any
+`Command`, `Arg`, or `PossibleValue` method can be used as an attribute.
+
+Raw attributes come in two different syntaxes:
+```rust
+#[clap(
+ global = true, // name = arg form, neat for one-arg methods
+ required_if_eq("out", "file") // name(arg1, arg2, ...) form.
+)]
+```
+
+- `method = arg` can only be used for methods which take only one argument.
+- `method(arg1, arg2)` can be used with any method.
+
+As long as `method_name` is not one of the magical methods - it will be
+translated into a mere method call.
+
+**Magic attributes** have post-processing done to them, whether that is
+- Providing of defaults
+- Special behavior is triggered off of it
+
+Magic attributes are more constrained in the syntax they support, usually just
+`<attr> = <value>` though some use `<attr>(<value>)` instead. See the specific
+magic attributes documentation for details. This allows users to access the
+raw behavior of an attribute via `<attr>(<value>)` syntax.
+
+**NOTE:** Some attributes are inferred from [Arg Types](#arg-types) and [Doc
+Comments](#doc-comments). Explicit attributes take precedence over inferred
+attributes.
+
+### Command Attributes
+
+These correspond to a `clap::Command` which is used for both top-level parsers and
+when defining subcommands.
+
+**Raw attributes:** Any [`Command` method](https://docs.rs/clap/latest/clap/type.Command.html) can also be used as an attribute, see [Terminology](#terminology) for syntax.
+- e.g. `#[clap(arg_required_else_help(true))]` would translate to `cmd.arg_required_else_help(true)`
+
+**Magic attributes:**
+- `name = <expr>`: `clap::Command::name`
+ - When not present: [crate `name`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-name-field) (`Parser` container), variant name (`Subcommand` variant)
+- `version [= <expr>]`: `clap::Command::version`
+ - When not present: no version set
+ - Without `<expr>`: defaults to [crate `version`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-version-field)
+- `author [= <expr>]`: `clap::Command::author`
+ - When not present: no author set
+ - Without `<expr>`: defaults to [crate `authors`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-authors-field)
+- `about [= <expr>]`: `clap::Command::about`
+ - When not present: [Doc comment summary](#doc-comments)
+ - Without `<expr>`: [crate `description`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-description-field) (`Parser` container)
+ - **TIP:** When a doc comment is also present, you most likely want to add
+ `#[clap(long_about = None)]` to clear the doc comment so only `about`
+ gets shown with both `-h` and `--help`.
+- `long_about = <expr>`: `clap::Command::long_about`
+ - When not present: [Doc comment](#doc-comments) if there is a blank line, else nothing
+- `verbatim_doc_comment`: Minimizes pre-processing when converting doc comments to `about` / `long_about`
+- `next_display_order`: `clap::Command::next_display_order`
+- `next_help_heading`: `clap::Command::next_help_heading`
+ - When `flatten`ing `Args`, this is scoped to just the args in this struct and any struct `flatten`ed into it
+- `rename_all = <expr>`: Override default field / variant name case conversion for `Command::name` / `Arg::name`
+ - When not present: `kebab-case`
+ - Available values: `camelCase`, `kebab-case`, `PascalCase`, `SCREAMING_SNAKE_CASE`, `snake_case`, `lower`, `UPPER`, `verbatim`
+- `rename_all_env = <expr>`: Override default field name case conversion for env variables for `clap::Arg::env`
+ - When not present: `SCREAMING_SNAKE_CASE`
+ - Available values: `camelCase`, `kebab-case`, `PascalCase`, `SCREAMING_SNAKE_CASE`, `snake_case`, `lower`, `UPPER`, `verbatim`
+
+And for `Subcommand` variants:
+- `skip`: Ignore this variant
+- `flatten`: Delegates to the variant for more subcommands (must implement `Subcommand`)
+- `subcommand`: Nest subcommands under the current set of subcommands (must implement `Subcommand`)
+- `external_subcommand`: `clap::Command::allow_external_subcommand(true)`
+ - Variant must be either `Variant(Vec<String>)` or `Variant(Vec<OsString>)`
+
+### Arg Attributes
+
+These correspond to a `clap::Arg`.
+
+**Raw attributes:** Any [`Arg` method](https://docs.rs/clap/latest/clap/struct.Arg.html) can also be used as an attribute, see [Terminology](#terminology) for syntax.
+- e.g. `#[clap(max_values(3))]` would translate to `arg.max_values(3)`
+
+**Magic attributes**:
+- `name = <expr>`: `clap::Arg::new`
+ - When not present: case-converted field name is used
+- `value_parser [= <expr>]`: `clap::Arg::value_parser`
+ - When not present: will auto-select an implementation based on the field type
+ - To register a custom type's `ValueParser`, implement `ValueParserFactory`
+ - When present, implies `#[clap(action)]`
+- `action [= <expr>]`: `clap::Arg::action`
+ - When not present: will auto-select an action based on the field type
+ - When present, implies `#[clap(value_parser)]`
+- `help = <expr>`: `clap::Arg::help`
+ - When not present: [Doc comment summary](#doc-comments)
+- `long_help = <expr>`: `clap::Arg::long_help`
+ - When not present: [Doc comment](#doc-comments) if there is a blank line, else nothing
+- `verbatim_doc_comment`: Minimizes pre-processing when converting doc comments to `help` / `long_help`
+- `short [= <char>]`: `clap::Arg::short`
+ - When not present: no short set
+ - Without `<char>`: defaults to first character in the case-converted field name
+- `long [= <str>]`: `clap::Arg::long`
+ - When not present: no long set
+ - Without `<str>`: defaults to the case-converted field name
+- `env [= <str>]`: `clap::Arg::env` (needs `env` feature enabled)
+ - When not present: no env set
+ - Without `<str>`: defaults to the case-converted field name
+- `flatten`: Delegates to the field for more arguments (must implement `Args`)
+ - Only `help_heading` can be used with `flatten`. See
+ [clap-rs/clap#3269](https://github.com/clap-rs/clap/issues/3269) for why
+ arg attributes are not generally supported.
+ - **Tip:** Though we do apply a flattened `Args`'s Parent Command Attributes, this
+ makes reuse harder. Generally prefer putting the cmd attributes on the `Parser`
+ or on the flattened field.
+- `subcommand`: Delegates definition of subcommands to the field (must implement `Subcommand`)
+ - When `Option<T>`, the subcommand becomes optional
+- `from_global`: Read a `clap::Arg::global` argument (raw attribute), regardless of what subcommand you are in
+- `parse(<kind> [= <function>])`: `clap::Arg::validator` and `clap::ArgMatches::values_of_t`
+ - **Deprecated:**
+ - Use `value_parser(...)` for `from_str`, `try_from_str`, `from_os_str`, and `try_from_os_str`
+ - Use `action(ArgAction::Count` for `from_occurrences`
+ - Use `action(ArgAction::SetTrue` for `from_flag`
+ - Default: `try_from_str`
+ - Warning: for `Path` / `OsString`, be sure to use `try_from_os_str`
+ - See [Arg Types](#arg-types) for more details
+- `value_enum`: Parse the value using the `ValueEnum` trait
+- `skip [= <expr>]`: Ignore this field, filling in with `<expr>`
+ - Without `<expr>`: fills the field with `Default::default()`
+- `default_value = <str>`: `clap::Arg::default_value` and `clap::Arg::required(false)`
+- `default_value_t [= <expr>]`: `clap::Arg::default_value` and `clap::Arg::required(false)`
+ - Requires `std::fmt::Display` or `#[clap(value_enum)]`
+ - Without `<expr>`, relies on `Default::default()`
+- `default_value_os_t [= <expr>]`: `clap::Arg::default_value_os` and `clap::Arg::required(false)`
+ - Requires `std::convert::Into<OsString>` or `#[clap(value_enum)]`
+ - Without `<expr>`, relies on `Default::default()`
+
+### Arg Enum Attributes
+
+- `rename_all = <expr>`: Override default field / variant name case conversion for `PossibleValue::new`
+ - When not present: `kebab-case`
+ - Available values: `camelCase`, `kebab-case`, `PascalCase`, `SCREAMING_SNAKE_CASE`, `snake_case`, `lower`, `UPPER`, `verbatim`
+
+### Possible Value Attributes
+
+These correspond to a `clap::PossibleValue`.
+
+**Raw attributes:** Any [`PossibleValue` method](https://docs.rs/clap/latest/clap/struct.PossibleValue.html) can also be used as an attribute, see [Terminology](#terminology) for syntax.
+- e.g. `#[clap(alias("foo"))]` would translate to `pv.alias("foo")`
+
+**Magic attributes**:
+- `name = <expr>`: `clap::PossibleValue::new`
+ - When not present: case-converted field name is used
+- `help = <expr>`: `clap::PossibleValue::help`
+ - When not present: [Doc comment summary](#doc-comments)
+
+## Arg Types
+
+`clap` assumes some intent based on the type used:
+
+| Type | Effect | Implies |
+|---------------------|--------------------------------------|------------------------------------------------------------------|
+| `bool` | flag | `#[clap(parse(from_flag))]` |
+| `Option<T>` | optional argument | `.takes_value(true).required(false)` |
+| `Option<Option<T>>` | optional value for optional argument | `.takes_value(true).required(false).min_values(0).max_values(1)` |
+| `T` | required argument | `.takes_value(true).required(!has_default)` |
+| `Vec<T>` | `0..` occurrences of argument | `.takes_value(true).required(false).multiple_occurrences(true)` |
+| `Option<Vec<T>>` | `0..` occurrences of argument | `.takes_value(true).required(false).multiple_occurrences(true)` |
+
+Notes:
+- For custom type behavior, you can override the implied attributes/settings and/or set additional ones
+ - For example, see [custom-bool](./custom-bool.md)
+- `Option<Vec<T>>` will be `None` instead of `vec![]` if no arguments are provided.
+ - This gives the user some flexibility in designing their argument, like with `min_values(0)`
+
+You can then support your custom type with `#[clap(parse(<kind> [= <function>]))]`:
+
+| `<kind>` | Signature | Default `<function>` |
+|--------------------------|---------------------------------------|---------------------------------|
+| `from_str` | `fn(&str) -> T` | `::std::convert::From::from` |
+| `try_from_str` (default) | `fn(&str) -> Result<T, E>` | `::std::str::FromStr::from_str` |
+| `from_os_str` | `fn(&OsStr) -> T` | `::std::convert::From::from` |
+| `try_from_os_str` | `fn(&OsStr) -> Result<T, E>` | (no default function) |
+| `from_occurrences` | `fn(u64) -> T` | `value as T` |
+| `from_flag` | `fn(bool) -> T` | `::std::convert::From::from` |
+
+Notes:
+- `from_os_str`:
+ - Implies `arg.takes_value(true).allow_invalid_utf8(true)`
+- `try_from_os_str`:
+ - Implies `arg.takes_value(true).allow_invalid_utf8(true)`
+- `from_occurrences`:
+ - Implies `arg.takes_value(false).multiple_occurrences(true)`
+ - Reads from `clap::ArgMatches::occurrences_of` rather than a `get_one` function
+ - Note: operations on values, like `default_value`, are unlikely to do what you want
+- `from_flag`
+ - Implies `arg.takes_value(false)`
+ - Reads from `clap::ArgMatches::is_present` rather than a `get_one` function
+ - Note: operations on values, like `default_value`, are unlikely to do what you want
+
+**Warning:**
+- To support non-UTF8 paths, you should use `#[clap(value_parser)]` otherwise
+ `clap` will parse it as a `String` which will fail on some paths.
+
+## Doc Comments
+
+In clap, help messages for the whole binary can be specified
+via [`Command::about`] and [`Command::long_about`] while help messages
+for individual arguments can be specified via [`Arg::help`] and [`Arg::long_help`]".
+
+`long_*` variants are used when user calls the program with
+`--help` and "short" variants are used with `-h` flag.
+
+```rust
+# use clap::Parser;
+
+#[derive(Parser)]
+#[clap(about = "I am a program and I work, just pass `-h`", long_about = None)]
+struct Foo {
+ #[clap(short, help = "Pass `-h` and you'll see me!")]
+ bar: String,
+}
+```
+
+For convenience, doc comments can be used instead of raw methods
+(this example works exactly like the one above):
+
+```rust
+# use clap::Parser;
+
+#[derive(Parser)]
+/// I am a program and I work, just pass `-h`
+struct Foo {
+ /// Pass `-h` and you'll see me!
+ bar: String,
+}
+```
+
+**NOTE:** Attributes have priority over doc comments!
+
+**Top level doc comments always generate `Command::about/long_about` calls!**
+If you really want to use the `Command::about/long_about` methods (you likely don't),
+use the `about` / `long_about` attributes to override the calls generated from
+the doc comment. To clear `long_about`, you can use
+`#[clap(long_about = None)]`.
+
+**TIP:** Set `#![deny(missing_docs)]` to catch missing `--help` documentation at compile time.
+
+### Pre-processing
+
+```rust
+# use clap::Parser;
+#[derive(Parser)]
+/// Hi there, I'm Robo!
+///
+/// I like beeping, stumbling, eating your electricity,
+/// and making records of you singing in a shower.
+/// Pay up, or I'll upload it to youtube!
+struct Robo {
+ /// Call my brother SkyNet.
+ ///
+ /// I am artificial superintelligence. I won't rest
+ /// until I'll have destroyed humanity. Enjoy your
+ /// pathetic existence, you mere mortals.
+ #[clap(long, action)]
+ kill_all_humans: bool,
+}
+```
+
+A doc comment consists of three parts:
+- Short summary
+- A blank line (whitespace only)
+- Detailed description, all the rest
+
+The summary corresponds with `Command::about` / `Arg::help`. When a blank line is
+present, the whole doc comment will be passed to `Command::long_about` /
+`Arg::long_help`. Or in other words, a doc may result in just a `Command::about` /
+`Arg::help` or `Command::about` / `Arg::help` and `Command::long_about` /
+`Arg::long_help`
+
+In addition, when `verbatim_doc_comment` is not present, `clap` applies some preprocessing, including:
+
+- Strip leading and trailing whitespace from every line, if present.
+
+- Strip leading and trailing blank lines, if present.
+
+- Interpret each group of non-empty lines as a word-wrapped paragraph.
+
+ We replace newlines within paragraphs with spaces to allow the output
+ to be re-wrapped to the terminal width.
+
+- Strip any excess blank lines so that there is exactly one per paragraph break.
+
+- If the first paragraph ends in exactly one period,
+ remove the trailing period (i.e. strip trailing periods but not trailing ellipses).
+
+Sometimes you don't want this preprocessing to apply, for example the comment contains
+some ASCII art or markdown tables, you would need to preserve LFs along with
+blank lines and the leading/trailing whitespace. When you pass use the
+`verbatim_doc_comment` magic attribute, you preserve
+them.
+
+**Note:** Keep in mind that `verbatim_doc_comment` will *still*
+- Remove one leading space from each line, even if this attribute is present,
+ to allow for a space between `///` and the content.
+- Remove leading and trailing blank lines
+
+## Tips
+
+- To get access to a `Command` call `CommandFactory::command` (implemented when deriving `Parser`)
+- Proactively check for bad `Command` configurations by calling `Command::debug_assert` in a test ([example](../tutorial_derive/05_01_assert.rs))
+
+## Mixing Builder and Derive APIs
+
+The builder and derive APIs do not live in isolation. They can work together, which is especially helpful if some arguments can be specified at compile-time while others must be specified at runtime.
+
+### Using derived arguments in a builder application
+
+*[Jump to source](augment_args.rs)*
+
+When using the derive API, you can `#[clap(flatten)]` a struct deriving `Args` into a struct deriving `Args` or `Parser`. This example shows how you can augment a `Command` instance created using the builder API with `Args` created using the derive API.
+
+It uses the `Args::augment_args` method to add the arguments to the `Command` instance.
+
+Crates such as [clap-verbosity-flag](https://github.com/rust-cli/clap-verbosity-flag) provide structs that implement `Args` or `Parser`. Without the technique shown in this example, it would not be possible to use such crates with the builder API. `augment_args` to the rescue!
+
+### Using derived subcommands in a builder application
+
+*[Jump to source](augment_subcommands.rs)*
+
+When using the derive API, you can use `#[clap(subcommand)]` inside the struct to add subcommands. The type of the field is usually an enum that derived `Parser`. However, you can also add the subcommands in that enum to a `Command` instance created with the builder API.
+
+It uses the `Subcommand::augment_subcommands` method to add the subcommands to the `Command` instance.
+
+### Adding hand-implemented subcommands to a derived application
+
+*[Jump to source](hand_subcommand.rs)*
+
+When using the derive API, you can use `#[clap(subcommand)]` inside the struct to add subcommands. The type of the field is usually an enum that derived `Parser`. However, you can also implement the `Subcommand` trait manually on this enum (or any other type) and it can still be used inside the struct created with the derive API. The implementation of the `Subcommand` trait will use the builder API to add the subcommands to the `Command` instance created behind the scenes for you by the derive API.
+
+Notice how in the previous example we used `augment_subcommands` on an enum that derived `Parser`, whereas now we implement `augment_subcommands` ourselves, but the derive API calls it automatically since we used the `#[clap(subcommand)]` attribute.
+
+### Flattening hand-implemented args into a derived application
+
+*[Jump to source](flatten_hand_args.rs)*
+
+When using the derive API, you can use `#[clap(flatten)]` inside the struct to add arguments as if they were added directly to the containing struct. The type of the field is usually an struct that derived `Args`. However, you can also implement the `Args` trait manually on this struct (or any other type) and it can still be used inside the struct created with the derive API. The implementation of the `Args` trait will use the builder API to add the arguments to the `Command` instance created behind the scenes for you by the derive API.
+
+Notice how in the example 1 we used `augment_args` on the struct that derived `Parser`, whereas now we implement `augment_args` ourselves, but the derive API calls it automatically since we used the `#[clap(flatten)]` attribute.

+
+Example of a busybox-style multicall program
+
+See the documentation for `clap::Command::multicall` for rationale.
+
+This example omits every command except true and false,
+which are the most trivial to implement,
+```console
+$ busybox true
+? 0
+
+$ busybox false
+? 1
+
+```
+*Note: without the links setup, we can't demonstrate the multicall behavior*
+
+But includes the `--install` option as an example of why it can be useful
+for the main program to take arguments that aren't applet subcommands.
+```console
+$ busybox --install
+? failed
+...
+
+```
+
+Though users must pass something:
+```console
+$ busybox
+? failed
+busybox
+
+USAGE:
+ busybox [OPTIONS] [APPLET]
+

+ -h, --help Print help information
+ --install <install> Install hardlinks for all subcommands in path

+
+[`pacman`](https://wiki.archlinux.org/index.php/pacman) defines subcommands via flags.
+
+Here, `-S` is a short flag subcommand:
+```console
+$ pacman -S package
+Installing package...
+
+```
+
+Here `--sync` is a long flag subcommand:
+```console
+$ pacman --sync package
+Installing package...
+
+```
+
+Now the short flag subcommand (`-S`) with a long flag:
+```console
+$ pacman -S --search name
+Searching for name...
+
+```
+
+And the various forms of short flags that work:
+```console
+$ pacman -S -s name
+Searching for name...
+
+$ pacman -Ss name
+Searching for name...
+
+```
+*(users can "stack" short subcommands with short flags or with other short flag subcommands)*
+
+In the help, this looks like:
+```console
+$ pacman -h
+pacman 5.2.1
+Pacman Development Team
+package manager utility
+
+USAGE:
+ pacman[EXE] <SUBCOMMAND>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ help Print this message or the help of the given subcommand(s)
+ query -Q --query Query the package database.
+ sync -S --sync Synchronize packages.
+
+$ pacman -S -h
+pacman[EXE]-sync
+Synchronize packages.
+
+USAGE:
+ pacman[EXE] {sync|--sync|-S} [OPTIONS] [--] [package]...
+
+ARGS:
+ <package>... packages
+
+OPTIONS:
+ -h, --help Print help information
+ -i, --info view package information
+ -s, --search <search>... search remote repositories for matching strings
+
+```
+
+And errors:
+```console
+$ pacman -S -s foo -i bar
+? failed
+error: The argument '--search <search>...' cannot be used with '--info'
+
+USAGE:
+ pacman[EXE] {sync|--sync|-S} --search <search>... <package>...
+
+For more information try --help
+
+```
+
+**NOTE:** Keep in mind that subcommands, flags, and long flags are *case sensitive*: `-Q` and `-q` are different flags/subcommands. For example, you can have both `-Q` subcommand and `-q` flag, and they will be properly disambiguated.
+Let's make a quick program to illustrate.

+
+## Quick Start
+
+You can create an application with several arguments using usage strings.
+
+[Example:](01_quick.rs)
+```console
+$ 01_quick --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 01_quick[EXE] [OPTIONS] [name] [SUBCOMMAND]
+
+ARGS:
+ <name> Optional name to operate on
+
+OPTIONS:
+ -c, --config <FILE> Sets a custom config file
+ -d, --debug Turn debugging information on
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ help Print this message or the help of the given subcommand(s)
+ test does testing things
+
+```
+
+By default, the program does nothing:
+```console
+$ 01_quick
+Debug mode is off
+
+```
+
+But you can mix and match the various features
+```console
+$ 01_quick -dd test
+Debug mode is on
+Not printing testing lists...
+
+```
+
+## Configuring the Parser
+
+You use the `Command` the start building a parser.
+
+[Example:](02_apps.rs)
+```console
+$ 02_apps --help
+MyApp 1.0
+Kevin K. <kbknapp@gmail.com>
+Does awesome things
+
+USAGE:
+ 02_apps[EXE] --two <VALUE> --one <VALUE>
+
+OPTIONS:
+ -h, --help Print help information
+ --one <VALUE>
+ --two <VALUE>
+ -V, --version Print version information
+
+$ 02_apps --version
+MyApp 1.0
+
+```
+
+You can use `command!()` to fill these fields in from your `Cargo.toml`
+file. **This requires the `cargo` feature flag.**
+
+[Example:](02_crate.rs)
+```console
+$ 02_crate --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 02_crate[EXE] --two <VALUE> --one <VALUE>
+
+OPTIONS:
+ -h, --help Print help information
+ --one <VALUE>
+ --two <VALUE>
+ -V, --version Print version information
+
+$ 02_crate --version
+clap [..]
+
+```
+
+You can use `Command` methods to change the application level behavior of clap.
+
+[Example:](02_app_settings.rs)
+```console
+$ 02_app_settings --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 02_app_settings[EXE] --two <VALUE> --one <VALUE>
+
+OPTIONS:
+ --two <VALUE>
+ --one <VALUE>
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 02_app_settings --one -1 --one -3 --two 10
+two: "10"
+one: "-3"
+
+```
+
+## Adding Arguments
+
+### Positionals
+
+You can have users specify values by their position on the command-line:
+
+[Example:](03_03_positional.rs)
+```console
+$ 03_03_positional --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_03_positional[EXE] [NAME]
+
+ARGS:
+ <NAME>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 03_03_positional
+NAME: None
+
+$ 03_03_positional bob
+NAME: Some("bob")
+
+```
+
+### Options
+
+You can name your arguments with a flag:
+- Order doesn't matter
+- They can be optional
+- Intent is clearer
+
+[Example:](03_02_option.rs)
+```console
+$ 03_02_option --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_02_option[EXE] [OPTIONS]
+
+OPTIONS:
+ -h, --help Print help information
+ -n, --name <NAME>
+ -V, --version Print version information
+
+$ 03_02_option
+name: None
+
+$ 03_02_option --name bob
+name: Some("bob")
+
+$ 03_02_option --name=bob
+name: Some("bob")
+
+$ 03_02_option -n bob
+name: Some("bob")
+
+$ 03_02_option -n=bob
+name: Some("bob")
+
+$ 03_02_option -nbob
+name: Some("bob")
+
+```
+
+### Flags
+
+Flags can also be switches that can be on/off:
+
+[Example:](03_01_flag_bool.rs)
+```console
+$ 03_01_flag_bool --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_01_flag_bool[EXE] [OPTIONS]
+
+OPTIONS:
+ -h, --help Print help information
+ -v, --verbose
+ -V, --version Print version information
+
+$ 03_01_flag_bool
+verbose: false
+
+$ 03_01_flag_bool --verbose
+verbose: true
+
+$ 03_01_flag_bool --verbose --verbose
+verbose: true
+
+```
+
+Or counted.
+
+[Example:](03_01_flag_count.rs)
+```console
+$ 03_01_flag_count --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_01_flag_count[EXE] [OPTIONS]
+
+OPTIONS:
+ -h, --help Print help information
+ -v, --verbose
+ -V, --version Print version information
+
+$ 03_01_flag_count
+verbose: 0
+
+$ 03_01_flag_count --verbose
+verbose: 1
+
+$ 03_01_flag_count --verbose --verbose
+verbose: 2
+
+```
+
+### Subcommands
+
+Subcommands are defined as `Command`s that get added via `Command::subcommand`. Each
+instance of a Subcommand can have its own version, author(s), Args, and even its own
+subcommands.
+
+[Example:](03_04_subcommands.rs)
+```console
+$ 03_04_subcommands help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_04_subcommands[EXE] <SUBCOMMAND>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ add Adds files to myapp
+ help Print this message or the help of the given subcommand(s)
+
+$ 03_04_subcommands help add
+03_04_subcommands[EXE]-add [..]
+Adds files to myapp
+
+USAGE:
+ 03_04_subcommands[EXE] add [NAME]
+
+ARGS:
+ <NAME>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 03_04_subcommands add bob
+'myapp add' was used, name is: Some("bob")
+
+```
+
+Because we set `Command::arg_required_else_help`:
+```console
+$ 03_04_subcommands
+? failed
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_04_subcommands[EXE] <SUBCOMMAND>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ add Adds files to myapp
+ help Print this message or the help of the given subcommand(s)
+
+```
+
+Because we set `Command::propagate_version`:
+```console
+$ 03_04_subcommands --version
+clap [..]
+
+$ 03_04_subcommands add --version
+03_04_subcommands[EXE]-add [..]
+
+```
+
+### Defaults
+
+We've previously showed that arguments can be `required` or optional. When
+optional, you work with a `Option` and can `unwrap_or`. Alternatively, you can
+set `Arg::default_value`.
+
+[Example:](03_05_default_values.rs)
+```console
+$ 03_05_default_values --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_05_default_values[EXE] [NAME]
+
+ARGS:
+ <NAME> [default: alice]
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 03_05_default_values
+NAME: "alice"
+
+$ 03_05_default_values bob
+NAME: "bob"
+
+```
+
+## Validation
+
+### Enumerated values
+
+If you have arguments of specific values you want to test for, you can use the
+`PossibleValuesParser` or `Arg::value_parser(["val1", ...])` for short.
+
+This allows you specify the valid values for that argument. If the user does not use one of
+those specific values, they will receive a graceful exit with error message informing them
+of the mistake, and what the possible valid values are
+
+[Example:](04_01_possible.rs)
+```console
+$ 04_01_possible --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 04_01_possible[EXE] <MODE>
+
+ARGS:
+ <MODE> What mode to run the program in [possible values: fast, slow]
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 04_01_possible fast
+Hare
+
+$ 04_01_possible slow
+Tortoise
+
+$ 04_01_possible medium
+? failed
+error: "medium" isn't a valid value for '<MODE>'
+ [possible values: fast, slow]
+
+For more information try --help
+
+```
+
+When enabling the `derive` feature, you can use `ValueEnum` to take care of the boiler plate for you, giving the same results.
+
+[Example:](04_01_enum.rs)
+```console
+$ 04_01_enum --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 04_01_enum[EXE] <MODE>
+
+ARGS:
+ <MODE> What mode to run the program in [possible values: fast, slow]
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 04_01_enum fast
+Hare
+
+$ 04_01_enum slow
+Tortoise
+
+$ 04_01_enum medium
+? failed
+error: "medium" isn't a valid value for '<MODE>'
+ [possible values: fast, slow]
+
+For more information try --help
+
+```
+
+### Validated values
+
+More generally, you can validate and parse into any data type.
+
+[Example:](04_02_parse.rs)
+```console
+$ 04_02_parse --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 04_02_parse[EXE] <PORT>
+
+ARGS:
+ <PORT> Network port to use
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 04_02_parse 22
+PORT = 22
+
+$ 04_02_parse foobar
+? failed
+error: Invalid value "foobar" for '<PORT>': invalid digit found in string
+
+For more information try --help
+
+$ 04_02_parse_derive 0
+? failed
+error: Invalid value "0" for '<PORT>': 0 is not in 1..=65535
+
+For more information try --help
+
+```
+
+A custom parser can be used to improve the error messages or provide additional validation:
+
+[Example:](04_02_validate.rs)
+```console
+$ 04_02_validate --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 04_02_validate[EXE] <PORT>
+
+ARGS:
+ <PORT> Network port to use
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 04_02_validate 22
+PORT = 22
+
+$ 04_02_validate foobar
+? failed
+error: Invalid value "foobar" for '<PORT>': `foobar` isn't a port number
+
+For more information try --help
+
+$ 04_02_validate 0
+? failed
+error: Invalid value "0" for '<PORT>': Port not in range 1-65535
+
+For more information try --help
+
+```
+
+### Argument Relations
+
+You can declare dependencies or conflicts between `Arg`s or even `ArgGroup`s.
+
+`ArgGroup`s make it easier to declare relations instead of having to list each
+individually, or when you want a rule to apply "any but not all" arguments.
+
+Perhaps the most common use of `ArgGroup`s is to require one and *only* one argument to be
+present out of a given set. Imagine that you had multiple arguments, and you want one of them to
+be required, but making all of them required isn't feasible because perhaps they conflict with
+each other.
+
+[Example:](04_03_relations.rs)
+```console
+$ 04_03_relations --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+

+
+### Custom Validation
+
+As a last resort, you can create custom errors with the basics of clap's formatting.
+
+[Example:](04_04_custom.rs)
+```console
+$ 04_04_custom --help
+clap [..]

+
+## Tips
+
+- For more complex demonstration of features, see our [examples](../README.md).
+- Proactively check for bad `Command` configurations by calling `Command::debug_assert` in a test ([example](05_01_assert.rs))
+
+## Contributing
+
+New example code:
+- Please update the corresponding section in the [derive tutorial](../tutorial_derive/README.md)
+- Building: They must be added to [Cargo.toml](../../Cargo.toml) with the appropriate `required-features`.
+- Testing: Ensure there is a markdown file with [trycmd](https://docs.rs/trycmd) syntax (generally they'll go in here).
+
+See also the general [CONTRIBUTING](../../CONTRIBUTING.md).

+
+## Quick Start
+
+You can create an application declaratively with a `struct` and some
+attributes. **This requires enabling the `derive` feature flag.**
+
+[Example:](01_quick.rs)
+```console
+$ 01_quick_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 01_quick_derive[EXE] [OPTIONS] [NAME] [SUBCOMMAND]
+
+ARGS:
+ <NAME> Optional name to operate on
+
+OPTIONS:
+ -c, --config <FILE> Sets a custom config file
+ -d, --debug Turn debugging information on
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ help Print this message or the help of the given subcommand(s)
+ test does testing things
+
+```
+
+By default, the program does nothing:
+```console
+$ 01_quick_derive
+Debug mode is off
+
+```
+
+But you can mix and match the various features
+```console
+$ 01_quick_derive -dd test
+Debug mode is on
+Not printing testing lists...
+
+```
+
+In addition to this tutorial, see the [derive reference](../derive_ref/README.md).
+
+## Configuring the Parser
+
+You use derive `Parser` the start building a parser.
+
+[Example:](02_apps.rs)
+```console
+$ 02_apps_derive --help
+MyApp 1.0
+Kevin K. <kbknapp@gmail.com>
+Does awesome things
+
+USAGE:
+ 02_apps_derive[EXE] --two <TWO> --one <ONE>
+
+OPTIONS:
+ -h, --help Print help information
+ --one <ONE>
+ --two <TWO>
+ -V, --version Print version information
+
+$ 02_apps_derive --version
+MyApp 1.0
+
+```
+
+You can use `#[clap(author, version, about)]` attribute defaults to fill these fields in from your `Cargo.toml` file.
+
+[Example:](02_crate.rs)
+```console
+$ 02_crate_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 02_crate_derive[EXE] --two <TWO> --one <ONE>
+
+OPTIONS:
+ -h, --help Print help information
+ --one <ONE>
+ --two <TWO>
+ -V, --version Print version information
+
+$ 02_crate_derive --version
+clap [..]
+
+```
+
+You can use attributes to change the application level behavior of clap. Any `Command` builder function can be used as an attribute.
+
+[Example:](02_app_settings.rs)
+```console
+$ 02_app_settings_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 02_app_settings_derive[EXE] --two <TWO> --one <ONE>
+
+OPTIONS:
+ --two <TWO>
+ --one <ONE>
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 02_app_settings_derive --one -1 --one -3 --two 10
+two: "10"
+one: "-3"
+
+```
+
+## Adding Arguments
+
+### Positionals
+
+You can have users specify values by their position on the command-line:
+
+[Example:](03_03_positional.rs)
+```console
+$ 03_03_positional_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_03_positional_derive[EXE] [NAME]
+
+ARGS:
+ <NAME>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 03_03_positional_derive
+name: None
+
+$ 03_03_positional_derive bob
+name: Some("bob")
+
+```
+
+### Options
+
+You can name your arguments with a flag:
+- Order doesn't matter
+- They can be optional
+- Intent is clearer
+
+The `#[clap(short = 'c')]` and `#[clap(long = "name")]` attributes that define
+the flags are `Arg` methods that are derived from the field name when no value
+is specified (`#[clap(short)]` and `#[clap(long)]`).
+
+[Example:](03_02_option.rs)
+```console
+$ 03_02_option_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_02_option_derive[EXE] [OPTIONS]
+
+OPTIONS:
+ -h, --help Print help information
+ -n, --name <NAME>
+ -V, --version Print version information
+
+$ 03_02_option_derive
+name: None
+
+$ 03_02_option_derive --name bob
+name: Some("bob")
+
+$ 03_02_option_derive --name=bob
+name: Some("bob")
+
+$ 03_02_option_derive -n bob
+name: Some("bob")
+
+$ 03_02_option_derive -n=bob
+name: Some("bob")
+
+$ 03_02_option_derive -nbob
+name: Some("bob")
+
+```
+
+### Flags
+
+Flags can also be switches that can be on/off. This is enabled via the
+`#[clap(parse(from_flag)]` attribute though this is implied when the field is a
+`bool`.
+
+[Example:](03_01_flag_bool.rs)
+```console
+$ 03_01_flag_bool_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_01_flag_bool_derive[EXE] [OPTIONS]
+
+OPTIONS:
+ -h, --help Print help information
+ -v, --verbose
+ -V, --version Print version information
+
+$ 03_01_flag_bool_derive
+verbose: false
+
+$ 03_01_flag_bool_derive --verbose
+verbose: true
+
+$ 03_01_flag_bool_derive --verbose --verbose
+verbose: true
+
+```
+
+Or counted with `#[clap(action = clap::ArgAction::Count)]`:
+
+[Example:](03_01_flag_count.rs)
+```console
+$ 03_01_flag_count_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_01_flag_count_derive[EXE] [OPTIONS]
+
+OPTIONS:
+ -h, --help Print help information
+ -v, --verbose
+ -V, --version Print version information
+
+$ 03_01_flag_count_derive
+verbose: 0
+
+$ 03_01_flag_count_derive --verbose
+verbose: 1
+
+$ 03_01_flag_count_derive --verbose --verbose
+verbose: 2
+
+```
+
+### Subcommands
+
+Subcommands are derived with `#[derive(Subcommand)]` and be added via `#[clap(subcommand)]` attribute. Each
+instance of a Subcommand can have its own version, author(s), Args, and even its own
+subcommands.
+
+[Example:](03_04_subcommands.rs)
+```console
+$ 03_04_subcommands_derive help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_04_subcommands_derive[EXE] <SUBCOMMAND>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ add Adds files to myapp
+ help Print this message or the help of the given subcommand(s)
+
+$ 03_04_subcommands_derive help add
+03_04_subcommands_derive[EXE]-add [..]
+Adds files to myapp
+
+USAGE:
+ 03_04_subcommands_derive[EXE] add [NAME]
+
+ARGS:
+ <NAME>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 03_04_subcommands_derive add bob
+'myapp add' was used, name is: Some("bob")
+
+```
+
+Above, we used a struct-variant to define the `add` subcommand. Alternatively,
+you can
+[use a struct for your subcommand's arguments](03_04_subcommands_alt.rs).
+
+Because we used `command: Commands` instead of `command: Option<Commands>`:
+```console
+$ 03_04_subcommands_derive
+? failed
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_04_subcommands_derive[EXE] <SUBCOMMAND>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ add Adds files to myapp
+ help Print this message or the help of the given subcommand(s)
+
+```
+
+Because we added `#[clap(propagate_version = true)]`:
+```console
+$ 03_04_subcommands_derive --version
+clap [..]
+
+$ 03_04_subcommands_derive add --version
+03_04_subcommands_derive[EXE]-add [..]
+
+```
+
+### Defaults
+
+We've previously showed that arguments can be `required` or optional. When
+optional, you work with an `Option` and can `unwrap_or`. Alternatively, you can
+set `#[clap(default_value_t)]`.
+
+[Example:](03_05_default_values.rs)
+```console
+$ 03_05_default_values_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 03_05_default_values_derive[EXE] [NAME]
+
+ARGS:
+ <NAME> [default: alice]
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 03_05_default_values_derive
+name: "alice"
+
+$ 03_05_default_values_derive bob
+name: "bob"
+
+```
+
+## Validation
+
+### Enumerated values
+
+If you have arguments of specific values you want to test for, you can derive
+`ValueEnum`.
+
+This allows you specify the valid values for that argument. If the user does not use one of
+those specific values, they will receive a graceful exit with error message informing them
+of the mistake, and what the possible valid values are
+
+[Example:](04_01_enum.rs)
+```console
+$ 04_01_enum_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 04_01_enum_derive[EXE] <MODE>
+
+ARGS:
+ <MODE> What mode to run the program in [possible values: fast, slow]
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 04_01_enum_derive fast
+Hare
+
+$ 04_01_enum_derive slow
+Tortoise
+
+$ 04_01_enum_derive medium
+? failed
+error: "medium" isn't a valid value for '<MODE>'
+ [possible values: fast, slow]
+
+For more information try --help
+
+```
+
+### Validated values
+
+More generally, you can validate and parse into any data type.
+
+[Example:](04_02_parse.rs)
+```console
+$ 04_02_parse_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 04_02_parse_derive[EXE] <PORT>
+
+ARGS:
+ <PORT> Network port to use
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 04_02_parse_derive 22
+PORT = 22
+
+$ 04_02_parse_derive foobar
+? failed
+error: Invalid value "foobar" for '<PORT>': invalid digit found in string
+
+For more information try --help
+
+$ 04_02_parse_derive 0
+? failed
+error: Invalid value "0" for '<PORT>': 0 is not in 1..=65535
+
+For more information try --help
+
+```
+
+A custom parser can be used to improve the error messages or provide additional validation:
+
+[Example:](04_02_validate.rs)
+```console
+$ 04_02_validate_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+ 04_02_validate_derive[EXE] <PORT>
+
+ARGS:
+ <PORT> Network port to use
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+$ 04_02_validate_derive 22
+PORT = 22
+
+$ 04_02_validate_derive foobar
+? failed
+error: Invalid value "foobar" for '<PORT>': `foobar` isn't a port number
+
+For more information try --help
+
+$ 04_02_validate_derive 0
+? failed
+error: Invalid value "0" for '<PORT>': Port not in range 1-65535
+
+For more information try --help
+
+```
+
+### Argument Relations
+
+You can declare dependencies or conflicts between `Arg`s or even `ArgGroup`s.
+
+`ArgGroup`s make it easier to declare relations instead of having to list each
+individually, or when you want a rule to apply "any but not all" arguments.
+
+Perhaps the most common use of `ArgGroup`s is to require one and *only* one argument to be
+present out of a given set. Imagine that you had multiple arguments, and you want one of them to
+be required, but making all of them required isn't feasible because perhaps they conflict with
+each other.
+
+[Example:](04_03_relations.rs)
+```console
+$ 04_03_relations_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:

+ -h, --help Print help information
+ --major auto inc major
+ --minor auto inc minor
+ --patch auto inc patch
+ --set-ver <VER> set version manually
+ --spec-in <SPEC_IN> some special input argument
+ -V, --version Print version information
+
+$ 04_03_relations_derive
+? failed
+error: The following required arguments were not provided:
+ <--set-ver <VER>|--major|--minor|--patch>
+

+
+For more information try --help
+
+$ 04_03_relations_derive --major
+Version: 2.2.3
+
+$ 04_03_relations_derive --major --minor
+? failed
+error: The argument '--major' cannot be used with '--minor'
+
+USAGE:
+ 04_03_relations_derive[EXE] <--set-ver <VER>|--major|--minor|--patch>
+
+For more information try --help
+
+$ 04_03_relations_derive --major -c config.toml

+error: The following required arguments were not provided:

+
+$ 04_03_relations_derive --major -c config.toml --spec-in input.txt
+Version: 2.2.3
+Doing work using input input.txt and config config.toml
+
+```
+
+### Custom Validation
+
+As a last resort, you can create custom errors with the basics of clap's formatting.
+
+[Example:](04_04_custom.rs)
+```console
+$ 04_04_custom_derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser

+ --minor auto inc minor
+ --patch auto inc patch
+ --set-ver <VER> set version manually
+ --spec-in <SPEC_IN> some special input argument
+ -V, --version Print version information

+
+## Tips
+
+- For more complex demonstration of features, see our [examples](../README.md).
+- See the [derive reference](../derive_ref/README.md) to understand how to use
+ anything in the [builder API](https://docs.rs/clap/) in the derive API.
+- Proactively check for bad `Command` configurations by calling `Command::debug_assert` in a test ([example](05_01_assert.rs))
+
+## Contributing
+
+New example code:
+- Please update the corresponding section in the [builder tutorial](../tutorial_builder/README.md)
+- Building: They must be added to [Cargo.toml](../../Cargo.toml) with the appropriate `required-features`.
+- Testing: Ensure there is a markdown file with [trycmd](https://docs.rs/trycmd) syntax (generally they'll go in here).
+
+See also the general [CONTRIBUTING](../../CONTRIBUTING.md).
